I guess I am the only one that burst out laughing when I saw fassbender at the end in that costume. I prefer the Mckellen magneto helmet by far!

No, you're not. Some costume designs just work better on page, and that helmet is one of them. That big splash of pink doesn't look at all intimidating and the whole helmet looks rather ill-fitting. Not to mention that giant hood ornament stuck to it that came out of nowhere. There's a reason that part isn't even done in the comics anymore.
